Answer 1

9:(9+7+8+6)=9:30=0,3

Answer 2

To find the probability that the first athlete to perform is from France, we need to calculate the ratio of the number of favorable outcomes (the number of French athletes) to the total number of possible outcomes (the total number of athletes).

Given that there are 9 athletes from France, 7 athletes from Italy, 8 athletes from Austria, and 6 athletes from Switzerland, the total number of athletes is:

9 (from France) + 7 (from Italy) + 8 (from Austria) + 6 (from Switzerland) = 30 athletes

Therefore, the probability that the first athlete to perform is from France is:

Number of favorable outcomes (French athletes) / Total number of possible outcomes (total athletes) = 9 / 30

Simplifying the fraction, we get:

Probability = 3 / 10

So, the probability that the first athlete to perform is from France is 3/10.
